Medieval diaries aid scientists ascertain increase in hot spots due to global warming

...published in Science reveals this week. The study finds that the number of 'hot spots' has increased dramatically in the Northern Hemisphere in the last century compared to the past 1200 years C adding to the growing evidence of wide-scale global warming. Dr Tim Osborn and Prof Keith Briffa, of the Climat...

Pitt professor's article considers nature as a service provider

A study published Feb. 1 in the journal Bioscience finds that giving economic value to environmental systems may actually help preserve those systems in the long run. The study, led by University of Pittsburgh Graduate School of Public and International Affairs (GSPIA) Professor Stephen Farber and titled "...

Illegal trade is propelling rare turtle toward extinction, new report

A new report released today finds that the illegal trade in the Roti Island snake-necked turtle, found only on one island in Indonesia, has left it all but extinct in the wild. Exotic pet enthusiasts in Europe, North America and East Asia are fueling the illegal trade for the turtle...

UCSD study finds anthrax toxins also harmful to fruit flies

...y contract the anthrax disease. However, the study finds that fruit flies can be used to test the effects of a single virulence factor, such as the LF or EF toxins, on signaling pathways shared by flies and humans. Guichard and her co-authors applied lethal factor toxin to fruit fly embryos and larvae and ...

Study implicates defective synapse generator in onset of Alzheimer's

...contribute to cognitive decline. The research team finds that blocking these PAKs in middle-aged mice causes memory loss together with deficits in a protein involved in making neuronal connections. In humans, the same protein shows large losses in Alzheimer as well as in Down syndrome, the most common caus...

Penguins okay with human visitors for now

...s the effects of humans on Magellanic Penguins and finds no immediate, negative effects of tourism. Although first seeing people is stressful for the penguins, habituation is rapid. The authors monitored the defensive head turns and the level of a hormone secreted in response to stress (plasma corticoster...

First demonstration of 'teaching' in non-human animals

...eaching. At the start of a tandem run, the leader finds a nave individual who is willing to follow her. But tandem runs are rather slow because the follower frequently pauses to look round for landmarks so that it can learn the route. Only when the follower has done this does it tap on the hind legs and a...

Extinctions linked to climate change

...udy being published Thursday in the journal Nature finds compelling evidence that global climate change created favorable conditions for a pathogenic fungus in Central and South America. That fungus, in turn, led to widespread extinctions of harlequin frogs at middle elevations of mountainous regions. In a...

Insects and mammals share common fat-building pathway, study suggests

...t in the Jan. 11, 2006, Cell Metabolism. The study finds that the so-called hedgehog (Hh) signaling pathway--an ancient suite of genes involved in determining the fates of many cell types--might also play an important role in fat formation in both flies and mice. The findings are the first to show a conser...

New biomimetic process used to grow artificial bone for better implants and prosthetics

...is means that, when implanted, the human body more finds it more difficult to distinguish the implant as a foreign object, hence reducing the chance if rejection. For implants in orthopedics or dental applications, such as hip and maxillae facial prostheses, which are typically made of titanium or cobalt a...

Realising potential of renewable resources wins Queens Award for University of York

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...with genetic damage. The liposome-antibody complex finds the cancer cell by binding to the transferrin receptor, which is present on the cancer cell surface in high numbers. When this happens, the p53 "payload" moves into the tumor cell. "If we are going to have an effective cancer therapy, we have to be...

Scientists observe how a close bond activates the immune system

...says Dr. Dustin. Once a T cell's antigen receptor finds an antigen match, the T cell forms an immunological synapse with a dendritic cell through which it queries the dendritic cell for additional information about the antigen and its source in the body. Is the antigen a danger or simply a harmless food p...

Missing fossil link 'Dallasaurus' found

... on display at the Dallas Museum. Major dinosaur finds are frequently the result of creatures dying in groups through flooding or drought, situations that lend themselves fairly well to more complete preservation and conservation of their bones, and much slower deterioration. Mosasaur fossils, in contras...

A meaty, salty, starchy diet may impact chronic lung disease

A new study finds that eating mostly meat, refined starches, and sodium may increase the likelihood of developing chronic respiratory symptoms, including chronic obstructive pulmonary disease (COPD). Researchers found that individuals whose diets are rich in meat, re...

Researchers uncover cellular clues to vitamin A resistance in lung cancer

... of the Journal of the National Cancer Institute finds that targeting a previously unknown variant of a common retinoid receptor may restore the beneficial effects of retinoids in lung cancer cells. Retinoids help regulate certain cellular functions in the body, such as cell growth and differentiation. T...

New and sharper X-rays of cell's ribosome could lead to better antibiotics

...art of the chromosomal DNA. Once the small subunit finds the start position, the "large" subunit moves in and latches on, clamping the mRNA between them. The combined machine slides along the mRNA, reading each three-letter codon, matching this code to the appropriate amino acid, and then adding that amino...

Modifications render carbon nanotubes nontoxic
